Thank you for the hint.
I've tried further, and still came up short. This time, if I use the % -
it returns nothing.
Here's the sample code I'm using:
?php
if (!subject) {
header(Location: nowhere.html);
exit;
}
// Connects to database
include(cnx_db.inc);
// First addslashes to text:
$formatted_subject = addslashes($subject);
// Formats Query
$sql = SELECT * FROM links WHERE (SUBJECT1='$formatted_subject' OR
SUBJECT2='$formatted_subject') AND GEOGRAPHIC='$geographic%'
ORDER BY ORGANIZATION ASC;
print($sql);
$sql_result = mysql_query($sql);
if (!$sql_result) {
echo Can't execute $sql . mysql_error();
exit;
}
// organizes data in an orderly manner (ie bulleted area)
while ($row = mysql_fetch_array($sql_result)) {
$esc_organization = $row[ORGANIZATION];
$esc_desc = $row[DESCRIPTION];
$esc_url = $row[URL];
$esc_subject1 = $row[SUBJECT1];
$esc_subject2 = $row[SUBJECT2];
$esc_geographic = $row[GEOGRAPHIC];
$organization = stripslashes($esc_organization);
$description = stripslashes($esc_desc);
$url = stripslashes($esc_url);
$subject1 = stripslashes($esc_subject1);
$subject2 = stripslashes($esc_subject2);
$geographic = stripslashes($esc_geographic);
$option_block .= libOrganization:/b a
href=\http://$url\;$organization/abrbGeographic Region:/b
$geographicbrbDescription:/b $descriptionbrbURL:/b a
href=\http://$url\;$url/a/librbSubject1:/b
$subject1brbSubject2:/b $subject2\n; } include(byebye.inc);
?
!DOCTYPE HTML PUBLIC -//W3C//DTD HTML 4.01 Transitional//EN

You have chosen ?php echo $subject; ?. Here are the results: Ul
?php echo $option_block; ? /UL
/body
/html
The printed SQL comes out like this:
SELECT * FROM links WHERE (SUBJECT1='Legislation' OR
SUBJECT2='Legislation') AND GEOGRAPHIC='%' ORDER BY ORGANIZATION ASC
Any ideas? Again, thanks for your help

Subject: RE: Fetching an optional array from an optional column
Hi,
Since you are using a form to query the table i assume the
subject1, subject and geographic will be variables. So, you
could do something like:
SELECT * FROM links WHERE (subject1='$sub1' OR
subject2='$sub2') AND GEOGRAPHIC like '$geo%'
In this way, if the user enters no value for the variable
$geo then the query statement will query with (WHERE
geographic like '%' ) clause which will mean any country.. On
the other hand, if the user enters a country name for the
$geo , say Canada, then the query statement will query with
(WHERE geopgrahic like 'Canada%') clause which will hit the
rows with Canada.

Subject: Fetching an optional array from an optional column
I'm working on a form that queries by selection in PHP, where
a user selects a subject and an optional selection of
geographic region to get information. Each database entry
will have 2 subject fields, Subject 1 being the main subject
and Subject 2 being the cross-subject, and a geographic
field, which is optional. A table is set up like this:
+--+--+--+--+--+-+
| ID | Organization | URL | SUBJECT1 | SUBJECT2 | Geographic |
+--+--+--+--+--+-+
| 1 | Acme | www | Math| English | Canada |
| 2 | Loony Toons | www | Comedy | Math| Brazil |
...
The idea is that the query will check the database to see if
$Subject has a match in either Subject1 or Subject2. The
geographic is an optional selection. If I select a country,
then that's fairly simple. However, if I select Math as a
subject, and left the Geographic option unselected, I want it
to select all records that has a match in either Subject1 and
Subject2, irregardless of the Geographic option.
I tried the following query:
SELECT * FROM links WHERE (SUBJECT1='Legislation' OR
SUBJECT2='Legislation') AND GEOGRAPHIC = ''
But it won't find the above records because the geographic is
not a blank field.
I could drop the .. AND GEOGRAPHIC part, but then if
someone does select a country, it won't take country into
consideration. How do I get it to select all records based on
the subject, irregardless of the country?
Thanks in advance,
Lmlweb
